Problems solved by technology

On the other hand, when the amount of flushing water is reduced in this way, there will be a problem that when the toilet with the flushing water tank device is an old type toilet, poor flushing will occur due to insufficient flushing water, or the sewer piping on the downstream side of the toilet will cause poor cleaning. Dirt, etc. are not easily washed away due to the restriction of the environment, and sometimes the amount of washing water has to be increased.
[0011] Regarding the above-mentioned problem, in the flushing water tank device described in Patent Document 1, the amount of flushing water is constant in the respective flushing modes
